Flingsmash bundles are usually good (the game is more or less free anyways), I know they've been on sale in the $20 range before. Just checked prices, nothing too good at the moment, but just wait patiently.
I would highly recommend not buying third party either, used is fine though. GameStop is having another B2G1 this weekend, if you wanna get in on that.
If you HAVE to shell out for one right now, try to find one of the LoZ: Skyward Sword bundles for $70. Much better deal than spending $40 on just the remote and it's GOLD!
